1 b all whom it may concern.

Be it known that I, Osoan ALsPAUoH, a citizen of the United States, residing at Kinsley,in the county of Edwards and State of Kansas, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to improvements in oil burners and is especially adapted to the use of oil-fuel in the fire-pots of stoves, ranges, furnaces and steam boilers.

The particular object of this invention is to improve the combustion of the gas that issues from the burner, by providing an air inlet that is concentric with the burner and deflected upon the gas jets.

A further object is to provide a burner having an air-inlet therethrough, thereby avoiding the usual form of construction wherein the air supply pipe is positioned to one side of the burner and obstructing the flame at that side.

With the above and other objects in view, the present invention consists in the combination and arrangement of the parts as will be more fully described hereinafter, shown in the accompanying drawings, and particularly pointed out in the appended claims it being understood, that changes in form, proportion, size and minor details, may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

These objects are attained by the means illustrated in the accompanying drawing, in which Figure l is a vertical sectional view of the burner within the tire-pot of a stove. Fig. 2 is a plan view of air deflector support. Fig". 3 is a bottom plan vie-w of the gas distributing ring, and Fig. 4 is a horizontal sectional view on the line 4+4 of Fig. 1.

Similar reference numerals in all of the figures of the drawing designate like parts.

As shown in the drawing, the device embodies a base plate 5, preferably having a turned-up edge 6, which forms a shallow receptacle or basin. Said base is provided with a tubular extension 7 whose aperture is extended through the base, and a shorter extension 8 arranged concentric and outside of the extension 7, forming a narrow annular chamber 9. Adapted to closely fit said lower edge.

around the extension 7 and be supported by the extension 8, is a gas-jet ring 10, having a conical upper surface 11 and shallow radial grooves 12 formed on its under side.

With the construction thus far described, together with the oil inlet pipe 13 which preferably enters the stove below the burner and connects with the annular chamber 9, is provided a burner that will generate gas that will issue from beneath the gas ring 10, and if ignited, will burn with a steady flame, but to cause the flame to spread to the walls of the fire pot, the following described air-deflector is provided.

Upon the top edge of the extension 7 is supported a spider ring 1% having a central post or support 15 provided with an extension 16 of smaller diameter than the post, forming a shoulder 17. A concave air deflector 18 provided with a central aperture 19 is supported upon the shoulder 17. The bottom edge of the depending wall 20 of this air-deflector preferably extends below the plane of the top edge of the extension 7, thereby forming an annular passageway 21 between said depending wall and said extension 7.

The operation of the device is as follows: Initially oil is fed through the pipe 13 to the chamber 9 and ignited at the point of contact of the ring 10 and the extension 8. As the walls become heated, the oil in the narrow chamber 9 is generated into gas which issues through the grooves 12 of the ring 10. The air passing upward through the extension 7 is heated in its passage, passes through the spider 14 and contacts with the top wall of the deflector 18 and is deflected downward by the depending wall 20. As the air passes downward it strikes the conical or inclined upper surface of the ring 11, uniting with the gas issuing from the burner, and with a tendency of spreading toward the walls of the fire pot. Thus is formed a burner that is highly efiicient, simple in construction, cheap to manufacture, and in which the oil and liquid fuel can be quickly generated into a vapor. The force of the air discharge upon the issuing gas, can be regulated by adjusting the deflector 18 upon the extension 16, thereby raising the lower edge of said deflector and widening the space between the gas ets and Should oil at any tlme overflow the rg'enernting chamber it wilt be emnrht by the dished base.

iitzn'ing thns toil d scribed the invention, What is claimed is:

1. fr burner, comprising :1 base, two intermini extension projecting upwardly from said base forming a generating chamber therehetiveen, one of said extensions extend ing higher than the other, and a burnerring' provided with radial grooves adapted to tit orer and around one of said extensions and be supported by the other extension.

It burner, roinprising :1 base, extensions having an air passage therethrongh and projecting from said base forming a generating ehznnber therebetneen, a burner ring having :1 eoni "21]. upper side supported at the top oi? said generating; chamber, and 1111 nir deflector having 11 depending periphern] wall supported upon one of said extensions.

3. It burner, comprising a base, extensions having an air passagetherethrongh and projecting from said base forming a generator chamber therebetween, one of said extensions extending higher than the other, a burner ring supported at the top of said generating chamber 011 one of said extensions, it spider ring supported upon the other extension, and an air deflector supported upon said spider lin In testimony whereof I afliz; my signm ture in presence of two Witnesses.
